Big Brother is watching you and one developer wants you to know about it. Big Brother in this case is Google who has a number of ways of tracking the browsing habits of users. Google’s reach extends outside their directly owned properties–such as Gmail, YouTube and Blogger–to third-party websites through the sites’ use Google Analytics, Google AdSense, embedded YouTube videos, and other Google-related API calls.

Google Alarm hopes to bring some visibility to exactly how much personal information Google is collecting through the use of visual and audible alerts while you browse. The Firefox add-in even keeps a running stat about the percentage of websites you visit that include Google tracking bugs. Two versions of the add-in are available including one with sound and one with sound disabled, making it work friendly. An “experimental” Chrome version is available as well.

Google Alarm was developed by Jamie Wilkinson in 2009 during the Transmediale festival. Source code for the add-in is available via GitHub.
